[0002] A composite packaging bag is composed of two or more materials with different characteristics, which are combined together through one or more dry composite processes to form a packaging material with specific functions. Through material compounding, this kind of packaging bag can improve various properties such as air permeability, moisture permeability, oil resistance, water resistance, and chemical resistance of the packaging material.

[0003] For example, the Chinese patent with the publication number CN215555543U discloses a packaging bag, which includes a packaging bag body. A bottom seal is provided at the bottom of the packaging bag body, a folding seam is provided at the bottom of the packaging bag body, folding openings are provided at the tops of the left and right sides of the packaging bag body respectively. A plurality of first connecting ribs are provided on the inner side surface of the bottom seal, and the plurality of first connecting ribs intersect vertically and horizontally to form a reinforcing rib mesh layer in a grid structure. One side surface of the reinforcing rib mesh layer is connected to the inner side surface of the bottom seal through an adhesive, and the other side surface of the reinforcing rib mesh layer is connected to a fixing plate layer through an adhesive. A plurality of second connecting ribs are provided on the outer side surface of the bottom seal, one side surface of the plurality of second connecting ribs is connected to the outer side surface of the bottom seal through an adhesive, and a PE layer is provided on the other side surface of the plurality of second connecting ribs. The other side surfaces of the plurality of second connecting ribs coated with the PE layer are all arranged in the same plane. The utility model can ensure multiple uses, thereby achieving the purpose of saving resources.

[0004] The above patent has the following problems:

[0005] There are some disadvantages when the above patent is in use. For example, when the above packaging bag is in use, various things placed inside it are mixed together. When a hotter item and a colder item are placed together, it will cause the colder item to heat up quickly, resulting in the defrosting and deterioration of the colder item and affecting the quality of the item. In view of this, we propose a heat-insulating composite packaging bag. Content of the Utility Model

[0006] The purpose of the utility model is to provide a heat-insulating composite packaging bag to solve the problems raised in the above background technique.

[0007] In view of this, the utility model provides a heat-insulating composite packaging bag, including:

[0008] A composite packaging bag body, in which fixing strips are symmetrically and fixedly installed. Limiting strips are inserted and installed in the fixing strips. A fixing frame is fixedly installed between the two limiting strips. The bottom of the fixing frame contacts the inner wall bottom of the composite packaging bag body, and EPE is fixedly installed in the fixing frame;

[0009] Two limiting components, the two limiting components are respectively located on two fixing bars and are respectively used to limit the positions of two limiting bars;

[0010] Four fixing blocks, the four fixing blocks are respectively fixedly installed on the front and back sides of the composite packaging bag body, the same drawstring is fixedly installed on two adjacent fixing blocks, and a fuzzy magic tape and a hook magic tape are respectively fixedly installed on the front and back sides of the inner wall of the composite packaging bag body, and the fuzzy magic tape and the hook magic tape are adhesively matched.

[0011] In this technical solution, when it is necessary to store items with a large difference in hot and cold temperatures, the items at two temperatures are respectively placed on both sides of the pearl cotton. Under the action of the pearl cotton, the temperatures of the two items can be isolated, and there will be no phenomenon that the hotter item melts the colder item, ensuring that both stored items can be well preserved;

[0012] When it is necessary to carry away the composite packaging bag body, the hook magic tape is pasted on one side of the fuzzy magic tape. At this time, the feeding port of the composite packaging bag body will be closed, and external dust will not enter the composite packaging bag body. Subsequently, the personnel can pick up the two drawstrings to carry away the composite packaging bag body;

[0013] When it is not necessary to store items with a large difference in hot and cold temperatures, through the provided limiting components, the fixing frame can be taken out upward, and the fixing frame drives the pearl cotton to be taken out, which is convenient for personnel to load a large number of items with the same temperature at one time.

[0014] In the above technical solution, further, the limiting component includes:

[0015] A rectangular block, the rectangular block is slidably installed on the top of the fixing bar, two sliding grooves II are symmetrically opened in the rectangular block, sliding bars are slidably installed in the sliding grooves II, two sliding grooves I are opened on the top of the fixing bar, the lower end of the sliding bar penetrates through the corresponding sliding bar and extends into the corresponding sliding groove I, and the lower end of the sliding bar is slidably connected with the corresponding sliding groove I. A plurality of springs are fixedly installed on the mutually remote sides of the two sliding bars and the inner walls of the corresponding sliding grooves II, the lower ends of the two sliding bars are inserted and matched with the limiting bars, and the upper ends of the two sliding bars respectively penetrate through the two sliding grooves II and extend into the composite packaging bag body.

[0016] In this technical solution, when there is no need to store items with a large difference in hot and cold temperatures, the user first pulls the two sliding bars on the left to slide and move away from each other. At the same time, several springs on the left are compressed and contracted. When the lower ends of the two sliding bars on the left both disengage from the left limiting bar, the user pulls the sliding bars to the left. The sliding bars drive the rectangular block to slide to the left. When the rectangular block slides to a suitable position, the user releases the two sliding bars. Under the action of the elastic force of several springs, the two sliding bars will slide and approach each other, and the two sliding bars are respectively inserted into the two sliding grooves I. At this time, the two sliding bars cannot slide left and right, further making the rectangular block unable to slide. After performing the above operations to slide the rectangular block on the right to the right, finally, the fixed frame is taken out upward, and the fixed frame drives the EPE to be taken out, which is convenient for personnel to load a large number of items with the same temperature at one time.

[0017] In the above technical solution, further, placing bags are fixedly installed on both the left and right sides of the composite packaging bag body.

[0018] In this technical solution, through the two placing bags provided, some frequently used items can be placed. When taking the items in the placing bags, there is no need to open the composite packaging bag body, which is convenient and fast to take.

[0019] In the above technical solution, further, sliding blocks are symmetrically and slidably installed at the top of the fixed bar, and the sliding blocks are fixedly connected to the bottom of the corresponding rectangular block.

[0020] In this technical solution, it is ensured that the sliding of the rectangular block will drive the corresponding two sliding blocks to slide to the left. Through the provided sliding blocks, the stability of the sliding of the rectangular block can be ensured.

[0022] In this technical solution, through the provided sliding bar, it is ensured that the sliding bar can fix the position of the corresponding limiting bar, and it is ensured that after the limiting bar is inserted into the corresponding fixed bar, the limiting bar can only slide up and down.

[0023] In the above technical solution, further, the fixed frame and the two limiting bars are of an integrally formed structure.

[0024] In this technical solution, the stability of the fixed frame and the two limiting bars during use is ensured.

[0025] The beneficial effects of the present utility model are:

[0026] 1. When storing items with a large temperature difference between hot and cold, place the items at the two temperatures on both sides of the pearl cotton respectively. Under the action of the pearl cotton, the temperatures of the two items can be isolated, and the phenomenon that the hotter item melts the colder item will not occur, ensuring that both stored items can be well preserved.

[0027] 2. When not storing items with a large temperature difference between hot and cold, through the provided limiting component, the fixing frame can be taken out upwards, and the fixing frame drives the pearl cotton to be taken out, which is convenient for personnel to load a large number of items with the same temperature at one time.
